Description

Technical Field

[0001] The utility model relates to the technical field of aerial photography equipment, in particular to an unmanned aerial vehicle (UAV) tilt photography platform. Background Art

[0002] Oblique photography technology is a high-tech technology developed in the international photogrammetry field in the past decade. It can not only truly reflect the situation of ground objects and obtain object texture information with high precision, but also generate realistic three-dimensional city models through advanced positioning, fusion and modeling technologies. UAV oblique photogrammetry uses oblique photogrammetry software systems to greatly reduce the time and cost of obtaining three-dimensional city models.

[0003] In the prior art, Chinese Patent Publication No. CN209870767U discloses an operating device for a tilt photography platform of an unmanned aerial vehicle with flexible and maneuverable multi-angle adjustment, comprising a drone body, wherein two brackets are fixedly connected to the bottom of the drone body. The operating device for a tilt photography platform of an unmanned aerial vehicle with flexible and maneuverable multi-angle adjustment, through the coordinated use of a first motor and a rotating block, the rotation of the first motor drives the rotating block to rotate, thereby causing a lens fixed on the rotating block to shoot as the rotating block rotates, and through the coordinated use of a pneumatic cylinder and an adjusting main rod, the output shaft of the pneumatic cylinder drives the adjusting main rod to rotate with a movable pin as the center of a circle, thereby driving and changing the angle of a second motor fixedly connected to the adjusting main rod, and at the same time, the output shaft of the second motor drives the lens to rotate, allowing the lens to shoot at multiple angles, increasing the shooting range, achieving the purpose of multi-angle adjustment, thereby improving shooting accuracy, improving work efficiency, and facilitating use.

[0004] However, when the existing drone tilt photography platform is taking photos in the air, sunlight will directly shine on the camera within a certain period of time, causing the camera to be blinded when taking pictures, thereby reducing the quality of the photos. In the existing technology, sun visors are used for shading, but this method not only increases the resistance of the flight, but also has a poor sun shading effect, so it needs to be improved.

When the first sun visor cannot completely cover the sunlight, the motor is started so that the motor drives the first gear to rotate, and the first gear is engaged with the second gear, thereby causing the second sun visor to flip around the second gear. The first sun visor is horizontal, and the motor drives the second sun visor to flip to an inclined state, thereby completely blocking direct sunlight and improving the sunshade effect for the camera. When the second sun visor is moving, the pulley will slide inside the arc slide rail, thereby being able to The two sides of the sun plate provide auxiliary support to improve the stability of the second sun visor during movement. When the second sun visor is tilted, air circulates through multiple ventilation holes, thereby reducing the resistance of the second sun visor during flight. The camera stand and camera are fixed at the lower position inside the mounting base, and the first sun visor and the second sun visor are arranged above the camera stand and camera. When fixing the mounting base on the drone, the staff will open holes on both sides of the bottom of the drone that are compatible with the bolts, and then thread the bolts into the interior of the mounting base so that the bolts extend into the holes of the drone, thereby fixing the mounting base. The spring is compressed by the insertion of the bolts, and the bolts form tension at this time. The two sides of the anti-slip gasket are in contact with the mounting base and the drone respectively, thereby preventing the bolts from loosening.

[0008] The present invention is further configured as follows: the number of the bolts is four, and the four bolts are distributed in the form of a rectangular array.

[0009] By adopting the above technical solution, four bolts are distributed at the four corners inside the mounting base to improve stability.

[0010] The beneficial effects of the utility model are:

[0011] When the second sun visor is in motion, the pulley will slide inside the arc slide rail, thereby providing auxiliary support for both sides of the second sun visor, thereby improving the stability of the second sun visor during movement.

[0012] 2. The utility model, through the arrangement between the ventilation holes, bolts, springs and anti-slip gaskets, allows air to circulate through the multiple ventilation holes when the second sun visor is in an inclined state, thereby reducing the resistance of the second sun visor during flight. When fixing the mounting base on the drone, the staff will open holes on both sides of the bottom of the drone that are compatible with the bolts, and then thread the bolts into the interior of the mounting base so that the bolts extend into the holes of the drone, thereby fixing the mounting base. The spring is compressed by the insertion of the bolts, and the bolts now form a tensioning force.
